Rev Med Liege 2020, 75(2),105-110Abstract : Late preterm infants are born between 34 weeks of amenorrhea and 36 weeks 6 days. Late preterms represent the largest proportion of premature infants (about 75 %). Late prematurity is increasing in recent decades. While studies initially focused on mortality and morbidity related to very preterm birth, the late preterms have been the subject of increased attention over the past 15 years. Late preterm infants have an increased risk of respiratory complications, infections, feeding problems, hypothermia and hypoglycemia. Neonatal, infant and during adulthood mortalities are significantly higher in late preterm than in term infants. In addition, late preterm infants carry an increased risk of long-term morbidities, such as neurodevelopmental delay, cerebral palsy, chronic respiratory or metabolic diseases. This review highlights the evidence that late preterm infants are high risk newborns and require adapted follow-up.
